It is worthy enough to understand the door lock types as for insuring your homes, the providers ask for the type of locks used in the external Aluminium doors.

1. Padlocks


These kinds of locks are detachable and are not permanently held to the door. A shackle attaches the lock to the door and is available in many sizes. They can be hinged or spring attached to the solid padlock body. Padlocks are so flexible to use as it is easily portable, lightweight, and easy to use. There are mainly two types of padlocks keyed and combination. For combination padlocks, we can set unique dails, and when the unique dial is matched, they open up.

The keyed type of padlock can be of two kinds, rekeyable and non-rekeyable. For non-rekeyable ones, you cannot change the key that can open the lock. While for the rekeyable locks, the key cylinder can be replaced, and a new key can be used. There are key retaining and non-key retaining types in padlocks. The former does not allow the key to be removed from the keypad when opened. On the other hand, later types enable the key to be separated once the lock is not engaged. Padlocks are comparatively easy to break by drilling or shimming activities.


2. Deadlocks 



Deadlocks are operated by using a key or simply by turning the knob. The different types of deadlocks include a single cylinder and double cylinder locks. They provide more security when compared to a regular lock. Deadlocks are used in conjunction with standard locks to enhance security. Deadbolts are made up of heavy metals like steel or brass and protrude significantly on the door. The keyless deadlocks are the trend in the market; they operate on credentials such as a pin code or a fingerprint.


Single-cylinder locks can be managed with a key only on one side, and the other end will have a knob that can be turned to operate the lock. For a double cylinder lock, there is a provision for using keys at either end. It cannot be opened just by turning the knob at the other end, which adds to the security of the whole system. The disadvantage of double cylinder locks is that in case of emergency, the ones inside won’t be able to exit if the door is locked from outside. So it is least recommended to be used in residential uses.


3. Access Control Locks


They are digital locks that work with a battery. They are usually seen in offices and for hotel rooms. The internal mechanism is similar to that of conventional locks.

Here the mechanism uses a mechanical combination with a numerical sequential combination to operate the Folding doors. Using a digital keypad along with these systems can give added security. If the wrong person enters the pin multiple times, the lock completely shutdowns, preventing the person from trying to break into it. In the digital keypad access system, each user can be assigned a unique code that is not possible with the conventional mechanical combination.


5. Magnetic Locks



Magnetic locks work with the principle of magnetic flux. The lock system contains a magnet plate and an armature plate. A magnetic flux generates when the current is passed through the magnet. This attracts the armature plate to it, and thus locking takes place. Once the current flow is interrupted, the system fails to provide security. However, they can be installed on doors which should be opened in case of emergencies like a fire. During a fire, the electricity goes off for a moment, and so doors get unlocked without any external force.


Magnetic locks provide reduced security compared to other locks. They are easy to install, as there are no connected parts. An uninterrupted power supply is required for the proper functioning of the lock system. The magnetic plate is mounted on the door frame and the armature part on the door. Magnetic doors are more expensive than other locks; even then, they provide low-level security.
